RWANDA GREEN GROWTH STRATEGY RWANDA’S FUTURE SOCIO-ECO-NOMIC DEVELOPMENT IS UNCERTAIN AS ITS POPULATION GROWS AND THE CLIMATE CHANGES. THIS STRATEGY IS THE FIRST ATTEMPT AT PLOT-TING A CLIMATE RESILIENT AND LOW CARBON DEVELOPMENT PATHWAY FOR RWANDA.RWANDA IS CHOOSING TO LEAP-FROG THE DETRIMENTAL DEVEL-OPMENT PATHWAYS OF THE PAST AND TAKE THE OPPORTUNITIES THAT TECHNOLOGY TRANSFER AND CLIMATE FINANCE OFFER.

POLICY IN PLACERWANDA GREEN GROWTH STRATEGY

GOAL 13CLIMATE ACTION TAKE URGENT ACTION TO COMBAT CLIMATE CHANGE AND ITS IMPACTS. CLIMATE CHANGE PRESENTS THE SINGLE BIGGEST THREAT TO DEVELOPMENT, AND ITS WIDESPREAD, UNPRECEDENTED EFFECTS DISPROPORTIONATELY BURDEN THE POOREST AND THE MOST VULNERABLE. URGENT ACTION IS NEEDED NOT ONLY TO COMBAT CLIMATE CHANGE AND ITS IMPACTS, BUT ALSO TO BUILD RESILIENCE IN RESPONDING TO CLIMATE-RELATED HAZARDS AND NATURAL DISASTERS.

GOAL 11SUSTAINABLE CITIES AND COMMUNITIES TODAY, MORE THAN HALF THE WORLD’S POPULATION LIVE IN CITIES. BY 2030, IT IS PROJECTED THAT 6 IN 10 PEOPLE WILL BE URBAN DWELLERS. DESPITE NUMEROUS PLANNING CHAL-LENGES, CITIES OFFER MORE EFFICIENT ECONOMIES OF SCALE ON MANY LEVELS, INCLUDING THE PROVISION OF GOODS, SERVICES AND TRANSPORTATION. GOAL 11 AIMS TO MAKE CITIES AND HUMAN SETTLEMENTS INCLUSIVE, SAFE, RESILIENT AND SUSTAINABLE.

GOAL 1NO POVERTY RWANDA MET MOST OF THE MILLENNIUM DEVELOPMENT GOALS (MDGS) BY THE END OF 2015. THE POVERTY RATE DROPPED FROM 44% IN 2011 TO 39% IN 2014 WHILE INEQUALITY MEASURED BY THE GINI COEF-FICIENT REDUCED FROM 0.49 IN 2011 TO 0.45 IN 2014.BUT CONTINUED WORK NEEDS TO BE DONE TO END TO POVERTY IN ALL ITS MANIFESTATIONS, INCLUDING EXTREME POVERTY. ONE WAY OF ACHIEVING THIS IS THROUGH CAPACITY-BUILDING AND CREATION OF NEW GREEN JOBS.

AT NIGHT, WHEN ARTIFICIAL LIGHT IS REQUIRED, WE WILL PROMOTE THE USE OF LED LIGHT-BULBS. LEDS USE ONLY ABOUT 10% OF THE ENERGY AN INCANDESCENT LAMP REQUIRES. IN ADDITION, IN THE LONG TERM THIS SAVES MONEY TO THE USER, AS THESE BULBS HAVE A MUCH LONGER LIFE-SPAN.

SOLAR WATER HEATERS A COST-EFFECTIVE WAY TO GENERATE HOT WATER. THEY ARE IDEAL FOR THIS CLIMATE AND THE FUEL THEY USE, SUNSHINE, IS FREE. THIS SYSTEM CAN PROVIDE THE HOT WATER OF A HOUSEHOLD FOR BOTH SHOWERING AND WASHING. THE HEATER AND THE SOLAR PANELS WILL BE INSTALLED ON THE ROOFS.
